FLASK.

To all whom it may concern:

Be it known that I, JAMES L.,BUTLER, a citizen of the United States, residing at Alliance, in the county of Stark and State of Ohio, have invented a new and useful Flask, of which the following is a specification.

My invention relates to improvements in foundry flasks, in which sheet metal, appropriately supported and reinforced, is used in the construction of the various parts of the flask and in which corrugated sheet metal is used for the lining, of said parts, and for the gaggers as hereinafter fully set out; and the objects of my improvement are, first, to provide a foundry flask having the qualities of durability and strength in combination with a comparative lightness in weight; second to provide a flask in which the sand will be firmly held by means of the corrugations extending around its inner surfaces and into which corrugations the sand may be readily l tucked. in the operation of ramming-up; 1 third to afford means for readily locating an adjustable gagger at any point throughout 3 the length of the flask. l. attain these objects together with others, which will be ap parent to those skilled in the art, by the construction illustrated in the accompanying drawing, in which- Figure 1 is a perspective view of a two part flask. showing my improvement, the cope and drag being illustrated as separated from each other, a portion of one of the sides of the cope being broken away. Fig. 2 is a transverse cross-section through the sides of the cop showing the construction of said sides and the arrangement of the gagger with relation thereto.

Similar numerals of reference indicate similar parts throughout the several views.

1 indicates a frame, each part of the flask having two such frames extending around its sides, the one at the top and the other at the bottom of the part as shown in the drawing. This frame may be formed of one con tinuous piece or may be formed in parts and secured together in any practical mechanical manner. Between the two frames of each part the flat sheet metal sides 2 extend entirely around the part. The edges of the sides 2 extend past the frame a short distance and may be returned or bent over as shown at Before the said edges 3 are bent or returned the corrugated lining 4 is placed on the inside of the flat sides 2, the I Specification of Letters Patent.

said lining 4 having at each edge a flattened portion 5 running throughout its length.

It will be understood that when the portion 3 of the sides 2 are returned or bent over they will engage the flattened portion 5 of the lining and tend to hold said lining in place. Rivets 6 are used to fasten the frame, the side 2, the lining 4 and the bent over portion 3 together, said rivets being arranged at intervals around each of the frames. If as a matter of practical manufacture it is thought best, rivets or other fastening devices 7 may be employed. at various places to fasten the corrugated lining to the sides 2 intermediate the frames 1. If it is desired, pieces of angle-iron may be at tached at the corners upon the outside of the sides 2 as shown at 8, the two sides of the angle extending in such way as to engage the two sides of the corner as shown, and also extending between the two frames to further 1 support them in their spaced relation to each other.

Upon two of the sides or ends of each part of the flask are arran ed an improved form of flask pin, together with a device whereby the part may be readily grappled by means of a suitable crane or hoisting attachment, whereby either part, but more usually the cope, may be lifted and turned over. Extending between the frames is the base portion 9, which is securely attached to the said frames. At each end of the said base portion is a portion extending at right angles to said base the same being numbered 10. The outside surface of the portion 10, it should be understood is in a plane with the side of the frame forming the edge of the part. On the part designed for the drag the upper portion 10 at each end is provided with a projecting pin 11. The lower portion 10 at one end of the drag is provided with a round hole such as shown on the cope at 12, which snugly fits the pins 11 on other parts, all such pins being of a uniform diameter. While at the other end of the said drag a hole 13 is arranged in the lower portion 10, said hole being of rectangular form, its width being equal to the standard diameter of the pins 11, and its length extending in a line with the flask pin attachment at the opposite end or side of the part, the length of said hole being somewhat greater than its width.

Extending from the base 9 intermediate the two portions 10, is the portion 14, which in transverse cross-section is round and is drilled hollow longitudinally at 15. It will be understood that this extension will afford ready 0 portunity for the attachment of a lifting evice by the insertion of a suitable pin into each of the portions 14, uponwhi'clr the part may be turned after it has been lifted into a free position.

On such parts as are especially designed for use as copes, no pins are provided on the portions 10, but the said portions are provided at one end with the round holes 12, such as previously described, and at the other with the rectangular holes 13, also previously described. It will thus be seen that by an appro riate selection of various parts provided wit '1 various appropriate flask pin devices as described, flasks of two, three or any desired number of parts may be built u pi n 10 of one part is brought into engagement with one of the holes 12 on the other part and the pin on the opposite side or end is then brought into engagement with the rectangular hole 13'. This will center the flasks properly, and at the same time will allow for slight variations for the pin registering with the round hole 12 will hold the parts in proper longitudinal and transverse relationship, but will allow slight adjustment longitudinally to accommodate variations in the parts.

Flasks of the construction herein disclosed may be made of different sizes as re quired and it will be understood that in case of the smaller sizes the projecting portion 14, may be omitted, as such smaller sizes may be easily handled without the use of any hoisting device.

The gagger or sand support 16 is constructed of corrugated material, preferably sheet metal, and consists in a corrugated sheet or strip extending from the corrugated lining of one side of the part to the corrugated lining of the other side.

At 17 at each end of the strip 16, the said strip is bent at right angles and the portion 18 is provided with transverse corrugations to match the corrugations of the lining of the part. The length of the strip 1.6 is such that it will be held rigidly in place by reason of the engagement of the corrugations on the bent portion 18 with the corresponding corrugations of the lining 4, when the said strip 16 is at right angles with the sides of the flask as shown in Fig. 1, and it will be understood that the gagger may be readily moved or taken from the part by disarranging' the position of one of its ends so as to destroy its transverse arrangement. In Fig. 2 the portion 18 is shown in engagement with the lining 4,, which lining is shown in cross section, and the arrangement and relation of the device to the side and lining of the part In placing one part upon the other, the

'will' be more fully understood by reference to said figure.

While I have shown the flask as constructed entirely of metal, it will be understood that any suitable material may be used for the various parts, and practically I the same construction may be employed for all sizes and shapes of flasks, and details of constructlon herein shown may be somewhat changed without departing from the true spirit of my invention.
